Bart Selman CS2800 10 Continuous vs. Discrete Math Why is it computer science? Mathematical techniques for DM What is CS 280 about?
Background image of page 10
Bart Selman CS2800 11 Discrete vs. Continuous Mathematics Continuous Mathematics It considers objects that vary continuously ; Example: analog wristwatch (separate hour, minute, and second hands). From an analog watch perspective, between 1 :25 p.m. and 1 :26 p.m. there are infinitely many possible different times as the second hand moves around the watch face. Real-number system --- core of continuous mathematics; Continuous mathematics --- models and tools for analyzing real-world phenomena that change smoothly over time. (Differential equations etc.)

Bart Selman CS2800 12 Discrete vs. Continuous Mathematics Discrete Mathematics It considers objects that vary in a discrete way. Example: digital wristwatch. On a digital watch, there are only finitely many possible different times between 1 :25 P.m. and 1:27 P.m. A digital watch does not show split seconds: no time between 1 :25:03 and 1 :25:04. The watch moves from one time to the next. Integers
